So, what is PUR glue? Well, it's a hot melt glue, yes, but what makes it different?
What is PUR Glue?
PUR glue is a specific type of hot melt glue.
PUR glue (polyurethane reactive glue) is a more recent development in the hot melt world. They polymerize when applied, forming a much stronger bond than other hot melts. It is quite flexible and can be used in a wider range of temperatures than most hot melts.
Advantages of Using PUR Glue
The bonds occur when the chemicals in the glue draw moisture out of the air. PUR glues are incredibly strong and flexible, and work beautifully as book binding adhesive using the perfect binding method on difficult jobs.
Like most hot melts, they tackify immediately, although PUR glues do require a 24-hour curing period. Common uses for PUR glue include bookbinding spine glue in certain binding applications. Other bookbinding methods depend on animal glue manufacturers like L.D. Davis for hide glue to get the job done correctly.
PUR glue is often used in the following industries:
- Printed film
LD Davis has been manufacturing eco-adhesives for over nine decades. In more recent years we have expanded our horizons to distribute hot melts, PUR glue, and other types of adhesives to fit your needs.
